Operation principle
It is a kind of photoelectric process on the process nature of optical signal storage, directly fiber-optic signal is recorded.The information sub-image that fiber-optic signal produces is a digitized electrostatic information picture being made up of electrostatic charge, and its charging, signal extraction process are by realizing based on electrostatic attraction principle.Owing to its electrostatic information sub-image is that photoconductive layer resistance reduces and causes charge discharge on charging film layer to be formed, so storage photosensitive drums is had following requirement: have the highest dark resistivity under light illumination.This storage photosensitive drums is in the case of unglazed photograph, and surface, once with the presence of electric charge, can preserve these electric charges for a long time；And in the situation of illumination, the resistivity of storage photosensitive drums should quickly decline, become the good conductor of electricity so that storage photosensitive drum surface electric charge quickly discharges and disappears.Storage photosensitive drums used in the present invention uses selenium and selenium alloy, zinc oxide, organic photoconductive material etc. to constitute, and is usually and is directly coated with or is deposited with a thin layer photoconductive material (such as aluminium sheet or other metallic plate) on conducting base.Its structure is to be photoconductive layer above, and conducting base is presented herein below.Its storage mode can be divided into charging, exposure typing, signal extraction, 4 basic steps of electric eliminating.
1, charging: charging makes storage photosensitive drums in the dark exactly, and be in the electric field of a certain polarity, it is made uniformly to bring the electrostatic charge of certain polarity and quantity, i.e. there is the process of certain surface current potential, this process actually stores the activation process of photosensitive drums, makes originally that not possessing photosensitive storage photosensitive drums has good photonasty.Charging process simply accepts what optical fiber information prepared for storage photosensitive drums, and this is premise and the basis forming electrostatic information sub-image at storage photosensitive drum surface.
When in the dark filling the uniform electrostatic charge of last layer to storage photosensitive drum surface, owing to storage photosensitive drums in the dark has higher resistance, so electrostatic charge is retained in storage photosensitive drum surface, i.e. storage photosensitive drums and maintains certain current potential and make it have photonasty.Photosensitive drums is stored for photoconductive material system of different nature and should be filled with the electric charge of opposed polarity, this be by the conduction of quasiconductor be determine, the most only allow the electric charge (hole or electronics) " injection " of a kind of polarity, and stop " injection " of another kind of polarity charge (electronics or hole).Therefore for N-type semiconductor, surface should be negatively charged；And to P-type semiconductor, then should be positive charged.When with positive corona to p-type storage photosensitive drums positive charged time, owing in P-type semiconductor, negative charge is immovable.Therefore the positive charge on photoconductive layer surface and the negative charge on interface, can only attract each other, without neutralizing.If negatively charged to p-type storage photosensitive drums with negative corona, then due to photoconductive layer and coboundary at, what sensing produced is positive charge, and the principal carrier of P type quasiconductor is " hole ", and easily the negative charge with storage photosensitive drum surface neutralizes.So, to p-type storage photosensitive drums negatively charged time, its charge efficiency is at a fairly low.Photosensitive drums is stored for N-type, is then electronics due to its principal carrier, if to its positive charged time, its charge efficiency is also the lowest, thus uses corona unit to be charged storage photosensitive drums.
2, exposure typing: exposure typing is that when utilizing storage photosensitive drums in the dark, resistance is big, becomes insulator；Time in the open, resistance is little, becomes the characteristic of conductor, is exposed typing to filling the storage photosensitive drums light image being.Storage photosensitive drums area of illumination surface charge disappears because of electric discharge；The area charge of unglazed photograph is according to keeping, thus forms the process of the electrostatic information sub-image that surface potential rises and falls with the change of image light and shade in storage photosensitive drums.When being exposed typing, the storage photosensitive drum surface of high-speed rotation is after optical fiber optical signal irradiates, optical fiber optical signal projects storage photosensitive drum surface through optical imaging system, and the part that photoconductive layer light is irradiated is referred to as " area pellucida ", and does not has the part natural number " dark space " that light irradiates.In area pellucida, photoconductive layer produces electron hole pair, i.e. generate photo-generated carrier, the resistivity making photoconductive layer reduces rapidly, good conductor is become by insulator, present conduction state, so that the current potential of storage photosensitive drum surface is quickly decayed because of photoconductive layer surface charge and the neutralization of interface reversed polarity electric charge.In dark space, photoconductive layer the most still presents state of insulation so that storage photosensitive drum surface current potential keeps constant.The height of storage photosensitive drum surface electrostatic potential is different with optical fiber optical signal strong and weak difference, the part surface current potential height that in storage photosensitive drums, corresponding optical signal is strong, and the weak part surface current potential of optical signal is low.So, just define, at storage photosensitive drum surface, the electrostatic information sub-image that a surface potential corresponding with optical output signal rises and falls.
3, information retrieval: information retrieval is exactly to make the electrostatic information sub-image in storage photosensitive drums be transformed into the process of the signal of telecommunication with charging neutrality.The information retrieval charged polarity of syringe needle is contrary with the charge polarity of storage photosensitive drum surface electrostatic information sub-image.During information retrieval, at storage photosensitive drum surface electrostatic information sub-image under the effect of electric field force, the part that electrostatic information sub-image current potential is the highest, adsorb the strongest to the ability of even-charge；The part that electrostatic information sub-image current potential is the lowest, absorbability is the most weak.The difference of corresponding electrostatic information sub-image current potential (electric charge number), its absorption antithesis quantity of electric charge is also the most different.So storage photosensitive drum surface sightless electrostatic information sub-image, has reformed into the signal of telecommunication of the visible voltage consistent with fiber-optic signal.After this voltage signal is amplified, it is achieved that and optical signal is stored the process extracted.
4, electric eliminating: electric eliminating is exactly the process eliminating information storage photosensitive drum surface residual charge.Before carrying out second time Data Enter, storage photosensitive drums must be carried out electric eliminating, make storage photosensitive drum surface current potential return to original state.The present invention uses exposure input device that storage photosensitive drums carries out blanket exposure typing, or with electric eliminating corona unit, storage photosensitive drums is carried out reverse polarity charging, to eliminate the residual charge in storage photosensitive drums.
